Yes, but whether you answer yes or no depends on the file. For /etc/passwd , /etc/shadow , /etc/group , and /etc/gshadow you generally would want to keep the original files. For .repo files or files about grub2 you generally want to accept the new files.
I just wrote this post because we have seen several users having this issue.
And the questions at the end are not always the same but the ones about those 4 files are almost always a part of this system upgrade.
